Roland's have no control over trigger options, just fingering ones.
But let us look a little closer... One thing to look for in peer reviews like this is common threads or complaints. The more people complain about a particular arranger's shortcomings, the more likely they are to have gotten it right.
To be honest, glitchy styles is NOT something that many have posted about. The weight... sure! The OS (nothing like Yamaha)... sure! The guitar sounds (especially in style mode)... sure.
But I don't recall much comment about that. Which begs the question... What is Zuki doing that no-one else did? This is hard to tell without an audio file. I wish we could hear Zuki play it, and see what is going on.
One thing to ask straight away... you say you are playing large complex jazz chords. Is that in two hands? Were you using the appropriate chord recognition system for that style of play? What is that system you ask? (Or actually, DIDN"T ask - anything - before you bailed)
I guess you're either overconfident that there is NOTHING a seasoned G70 player could tell you that you couldn't figure out for yourself, or unwilling to ask for help, but you end up reporting your problems LONG after you've already publicly announced your disdain for the G70 and your intention to drop it.
Kudos... after getting into this business relatively recently, it's nice to know that there is NOTHING that anyone needs help you with... Me, I get a new arranger, first thing I do is ASK those that already have said arranger if the problems I'm bumping into have a solution. Or if it's just me not grasping the OS and operation correctly. I guess that makes me a moron.
But a happy one, rather than dissatisfied.
And, you know what? Should I get an S900, I WILL ask Zuki, and Donny, and anyone else who'll talk with me about the issues I'm having, LONG before I issue a pronouncement about what a piece of rubbish it is, and by inference, what idiots you all are to use such a flawed piece of kit....
But that's just me... I'm no expert
